This indicator prioritizes areas for new land protection within the Mississippi Alluvial Valley (MAV) based on benefits to forest breeding birds that depend on large interior cores of bottomland hardwood habitat (Swainson’s warbler, cerulean warbler, swallow-tailed kite). The model considers core size, the amount of existing protected land within the forest patch, proximity to reforestation priority areas, and risk of conversion to agriculture based on flooding frequency. The highest scores represent drier, unprotected forest patches with cores at least 2,000 ha (~5,000 ac) that are adjacent to priority areas from a complementary reforestation model also developed by the Lower Mississippi Valley Joint Venture (LMVJV)....

The Southeast Conservation Blueprint is the primary product of the Southeast Conservation Adaptation Strategy (SECAS). It is a living, spatial plan to achieve the SECAS vision of a connected network of lands and waters across the Southeast and Caribbean. Southeast Blueprint 2023 identifies priority areas based on a suite of 61 natural and cultural resource indicators representing terrestrial, freshwater, and marine ecosystems. A connectivity analysis identifies corridors that link coastal and inland areas and span climate gradients. The Blueprint is regularly updated to incorporate new data, partner input, and information about on-the-ground conditions. The 2023 Blueprint expanded consistent methods and indicators...

The South Atlantic Conservation Blueprint is a living spatial plan to conserve natural and cultural resources for future generations. It identifies shared conservation priorities across the South Atlantic region.Blueprint 2021, released in August 2021, is a totally data-driven plan based on terrestrial, freshwater, marine, and cross-ecosystem indicators. It uses the current condition of those indicators to prioritize the most important areas for natural and cultural resources across the South Atlantic geography. Through a connectivity analysis, the Blueprint also identifies corridors that link coastal and inland areas and span climate gradients. The Blueprint reflects extensive feedback from the broader cooperative...

This indicator represents the size of large, unfragmented patches of natural habitat. It identifies minimally disturbed natural areas at least 100 acres in size and greater than 200 meters wide. This indicator originates from Esri’s green infrastructure data.Reason for SelectionLarge areas of intact natural habitat are favorable for conservation of numerous species, including reptiles and amphibians, birds, and large mammals. The Esri Green Infrastructure data covers the entire United States and has been used in other broad-scale conservation planning efforts, so using this existing data helps align the Blueprint with other conservation efforts and reduce duplication of effort. We chose to use “Core Size (acres)”...

This layer depicts the mosaiced, rebalanced Zonation results for each subregion in Base Blueprint 2022.OVERALL APPROACHThe Base Blueprint indicators (available on the Blueprint page of the SECAS Atlas) were modeled at a 30 m resolution, tested and reviewed, and used as inputs to identify priority areas for a connected network of lands and waters. To aid in the modeling process, we first removed highly altered areas, like most developed areas, as well as reservoirs. Generally, these areas would not be prioritized in the Blueprint anyway.The indicators then served as inputs into Zonation, a conservation planning framework and software program that produces a hierarchical prioritization of the landscape. We ran Zonation...
